Impact of Storage on the Biochemical Characterization of Commercial Fruit Beverages | Chapter 7 | Current Perspectives in Agriculture and Food Science Vol. 8

 

In the present era of processed and convenient food, ensuring the safety and hygienic quality of food products is very important. Several processed foods from fruits like fruit juices and fruit beverages are becoming popular under different brands due to their pleasing flavour, taste, and nutritional characteristics. Despite the potential benefits of fruit beverages, concerns over their safety and quality have been raised. According to the research data published in many countries, food intoxication is increasing due to different food additives and contaminants present in processed foods. Studies also showed that commercial fruit products like juice and jam available in the market were adulterated by harmful food colours, low-grade fruits and harmful preservatives which are harmful to health. So, processed food products including commercial fruit beverages should be adequate not only in terms of quantity but also of good quality, free from microbial and chemical contamination. Studies on commercial fruit beverages were conducted for different parameters like food additives, chemical, and microbial contamination for different storage periods. During storage, several changes may occur in food and beverages when it is exposed to different environmental conditions that may trigger a series of reactions on different biochemical and microbial parameters. So, it is the need of the hour to focus the attention of regulatory authorities on the shelf life and contamination of beverages with synthetic additives, microbes and heavy metals and help uninformed consumers make a healthful choice.

Remediation Rates of Microbes in Polluted Crude Oil Soil | Chapter 6 | Current Perspectives to Environment and Climate Change Vol. 4

 

Removal rate of Total Petroleum Hydrocarbon Content (TPHC) of a crude oil polluted land was
investigated with field experimental data generated from the Research Farm soil at the Federal
University of Technology Owerri, Imo State, Nigeria. The artificially polluted soil using crude oil -
bonny light - with specific gravity of 0.8323 was analyzed. The petroleum contaminant present in the
laboratory soil was 230 mg per kilogram of soil. The other treatment variables used include: Inorganic
fertilizer -FZ (NPK 20:10:10), poultry manure -MP, cow dung -CD and a mixture of the three (ie FZ,
PM & CD) in equal proportion. In addition, natural treatment was allowed to occur as the control
experiment. However, fungi as well as bacteria played an important role in the degradation of
petroleum hydrocarbon. The identified crude oil degrading Fungi are
Penicillium notatum, Mucor spp,
Rhizopus stolonifer and Penicillum caseicolum with P. notatum and P. caseicolum (penicillum spp) as
the strongest fungi degraders. On the other hand, the identified degrading Bacteria are
Pseudomonas
putida
and Bacillus subtilis. These can therefore be isolated and cultured and then employed on
remediation sites either as indigenous or foreign degrading microbes in the engineering of
bioremediation of crude oil polluted soil using the best engineering techniques. The treatment with
mixture of treatment variables proved to be a better option from the results obtained with 82.38 mg/kg
after 9 weeks of remediation followed by fertilizer, 83.13 mg/kg and 86.75 mg/kg for poultry manure.
Cow dung had 105.5 mg/kg and the control had least with 204.50 mg/kg.
